“…Dong et al [7] have reported that upon the addition of 7 wt% Y, the ultimate tensile strength and yield strength of the Mg-7Li alloy become 120% and 152% of those of the as-cast Mg-7Li alloy, respectively. Moreover, addition of alloying elements such as Al and rare-earth elements such as Nd, Re, and Pr to Mg-based alloys results in grain refinement, grain boundary strengthening, and solid-solution strengthening [8][9][10][11] and a consequent improvement of the corrosion resistance of the alloys. Such improved Mg-based alloys can be used for manufacturing aerospace components, automobile parts, electronic goods, and sports goods [12,13].…”
